' WATER HEATER.

Application filed June 21,

My invention pertains to water-heaters in association with furnaces orboilers, and aims to provide a simple and efficient-structure which mayor may not be used, as desired, and without in any way interfering withthe usual and proper functions of such furnace or boiler.

A. further purpose of the invention is the production of a structure ofthis character wherein the water tubes for the heater may be cleanedwith facility and dispatch, and without disturbing other material orsubstantial parts of the appliance. To enable those skilled in this artto have a full and complete understanding of this invention, both fromstructural and func- ,tional standpoints, in the accompanying drawings,forming a part of this specification and throughout the several views ofwhich like reference characters have been employed to designate the sameparts, a present desirable and preferred embodiment of the invention hasbeen illustrated.

In these drawings,

Figure 1 isa front or side elevation of the improved structure withparts broken away to more clearly show the internal construction;

Figure 2 is an end elevation of the appliance with some members shown insection;

Figure 3 is an enlarged fragmentary view of a part of the applianceshowing one of the detachable connectors for operably joining togetherthe ends of adjacent pipes or tubes; and

Figure 4 is a vertical section on line H of Figure 3.

Referring to these drawings, it will be perceived that the boiler has anouter, sheetmetal shell 11 and a corresponding inner, sheet-metal wall12 spaced inwardly away therefrom asuitable distance to provide side andend water-legs 13 and 14, and the top:

1926. Serial No. 117,445.

Similarly an upper baflie-wall 19 rests on the topmost row of such pipesor tubes extending fully to the right-hand vertical wall of the boiler,but having a corresponding gap or passage 21 at the left-hand portion;of the structure, whereby the heated gases their interiors being incommunication and hence providing for the proper and eflicient flow ofthe water therein, such wall 22 dividmg that-portion of the boiler intotwo chambers, one of which'is equipped with any approved form of liquidor gaseous fuel-burner 23, while the other is fitted with a grate 24:and suitable doors 25, 26 and 27, in the front or side wall associatedtherewith.

'fhlS grate may be used to burn fuel on. or it may be employed for thedrying and mclneration of garbage or the like.

At one end the furnace or boiler is fitted wlth a connection 28 adaptedto be joined .in the usual way with a stack or chimney for the dischargeof the gases.

As will be-readily understood, the eflicient and satisfactory oil or gasburner 23 has the grate 24 adjacent to it and which may be used tosupport the garbage or' other refuse while it is being dried out by theheat generated at such contiguous ,or adjoining burner and on which itmay be consumed after it has been sufficiently freed fronr moisture inthis manner.

Such grate may, at times, if desired, be employed for the burning ofcoal, coke, wood or other fuel, to supplement or augment theheating-action of the adjacent fluid-burner, or as a substitute thereforif required.

If preferred, the liquid or gas fuelburner, may be of such capacity asto provide adequate heat under all circumstances, or it may be of'lessersize or power and supplemented in its'heating function under extreme orunusual conditions, as by weather of very low temperature, by thecombustion of fuel on the nearby auxiliary grate, where- .by the heatingsurfaces of the appliance under such circumstances are subjected to thejoint action of both heating means. Or,

'if wanted, as for instance, if it were temporarily impossible to securefuel for the fluid burner, the grate may be used alone for sustainingthe solid fuel undergoing combustion.

The two heating means are so located and the baffle-walls are soarranged that substan tially the entire heating surfaces of the appliance are subjected to the action of the L ends of these heatgenerated by each.

So far as this portion of the structure is concerned, it is aimed toprovide a construction which is simple in character, which operatesefficiently, and which needs little attention, which is unlikely tobecome injured or damaged in ordinary service, and which may "bemanufacturedeconomically.

5 The water-heater associated. with this boiler or furnace comprises aplurality of horizontal water-pipes 3131, located in the water space orwater jacket in the divisionwall 22, and extended through thewaterspaces in the side legs of the boiler, and their metal walls, suchpipes being expanded. in the usual way to fit their holes in the innerand outer casings in fluid-tight manner.

Hence the water in these pipes has no direct connection with that in thelegs of the' 1furnace, or that in the cross divisionwal The water to beheated, as distinguished from that in the boiler, is admitted to thesepipes through a suitable manifold 32, secured against the outer face ofthe boiler in liquid-tight manner, in any approved way, and the water isfed into such manifold through an admission or inlet pipe 33 preferablyequipped with a control valve 34.

At the opposite end of the boiler, the other pipes are connectedtogether in like paralle relation by a manifold 35,

and hence, -it will be seen that these pipes,

j three in number, in the present instance, are

connected together in multiple.

A series or horizontal ro.w' of water-pipes "36 extend through the waterin the lower portion of the top space 15 of the boiler, and

through apertures in its sheet-metal endwalls, being expanded. orenlarged in the.

latter to form tight fits, as is customary.

These pipes are joined together inseries relation, rather than inparallel or multiple manner, and, to this end, the manifold 35 isconnected by a pipe 37 to a connection 38 bolted against the outer faceor wall of the boiler, with a suitably interposed gasket, in registerwith one end of the outermost pipe of the series, by means of stud bolts39 b0 ted in the metal wall and accommodated in apertures of lugs 41outstanding from the. connection, nuts being used on such studs,

by a hollow fitting 42 similar to that desig-' nated 38, but largeenough to cover the ends of two adjoining pipes.

By means of such fittings which are held in place by similar studs andnuts with intervening gaskets, all of these upper pipes are joinedtogether in series or serpentine relation, and the last pipe thereof isconnected in similar manner to a discharge pipe 43 by means of which thehot Water is conveyed to the place where it is to be used.

Thus the water entering through the pipe 33 leaves by means of pipe 43,having been suitably heated during its traverse through the pipeconnections in the lower and upper portions of the boiler and all ofwhich are immersed in and surrounded by difierent portions of the mainbody of water in such boiler.

This piping arrangement for the hot water provides means for the quickdistribu- One advantage of this construction resides in the fact, that,if such hot water-heater is not desired to be laced in service, thenthepipes 31 and 36 forming parts thereof and originally installed in theboiler when manufactured, are not connected up for use and no harmresults.

Furthermore, all of these hot water-heater pipes or tubes are readilyaccessible for.

cleaning by merely removing the exterior manifolds or connections whichgive easy access to the full lengths of all of the pipes,

vsuch members being readily removable and replaceable, as will beunderstood.

This invention is not limited and restricted to the precise and exactdetails of structure illustrated and described and may be incorporatedin physical form in several different ways, allinvolving the principlesof the in vention or stated otherwise, many mechanical changes ma bemade in the structure set' forth without eparture' from the heart andessence of the invention, and without the sacrifice of any of itsmaterial benefits and advantages.

I claim: 1. The combination of a boiler having I outer walls and adaptedto containa body of water, said boiler in its lower portion having twocombustion chambers separated from one another-by a hollow wall ada tedto contain water, a lower pipe exten ed through the water of said hollowwall, upper pes extended through said first mentioned body of water andthrough the opposite walls of the boiler, means outside of said wallsconnecting said upper pipes together, means connectm said lower pipe tosaid upper pipes, an means to feed water to said lower 1,es1,5sa

pipe, whereby the water may be heated in flowing through said lower pipeand upper pipes.

2. The combination of a boiler having outer walls and adapted to containa body of water, said boiler in its lower portion having two combustionchambers separated from one another by a hollow wall adapted to containwater, a plurality of lower pipes connected together in multiplerelationand extended through the water of said hollow wall, upper pipes extendedthrough said first mentioned body of water and through the oppositewalls of the boiler, means outside of said walls connecting said upperpipes together in series relation, means connecting said lower pipes tosaid upper pipes, and means to feed water to saidilower pipes, wherebythe water may be heated in flowing through said lower and upper pipes.

In witness whereof I have hereunto set my hand.
